to test a curcuit board here that runs the temp control on my cooling fans for my UHF homebase, what setting should i put my multimeter on? its a 12 volt unit if that helps

What do you want to test? The circuit board itself, or a specific component on the board etc?

i want to test the componants to see wich one blew up when it shorted out! its one of those jaycar ones and it sliped of the top of my linear and touched the metal body so something has blown on the board and it wont work!

There is a variety of components that need different tests to determine what is at fault. Realistically you will need to use about 1/2 of the total number of scales on your multimeter, and know what you are looking for.
No disrespect, but take it to someone that knows what they are doing.

most things can be tested for continuity of circuit by setting your meter to ohms and selecting the right range

Continuity is one thing, but without knowing the specific voltage range at a particular point of a circuit, you might as well guess. If it's a Jaycar unit, try Google to see if there's any testing/test point info on the web.
